TLP Battery Boost

Version 1.2.0

TLP Battery Boost is a lightweight Tkinter-based GUI for Linux laptops that optimise battery longevity with TLP. It is particularly useful for users who typically preserve battery health via configured charging thresholds but occasionally require a full charge.

TLP Battery Boost provides a simple interface for switching between:

  • Balanced Charging: TLP threshold-controlled charging behaviour.
  • Full-Charge Boost: Temporary override to charge thresholds.

How it works:

Battery Boost reads your TLP battery thresholds and charging state using tlp-stat.

Clicking the button applies a temporary override to the TLP controlled charging thresholds. This allows the battery to charge to 100%.

By default, TLP restores the configured thresholds on the next reboot, or when Battery Boost re-applies them by pressing the button again.

Optionally, if the configuration option RESTORE_THRESHOLDS_ON_BAT is enabled, thresholds are restored when AC power is disconnected.

For further details, refer to the TLP documentation.

Features

  • Simple one-click toggle between configured battery-care thresholds and a full-charge override.
